This example describes how php collects the proxy server network in China. Share it with you for your reference. The details are as follows:

<? Php/*** collect the latest list of proxy servers in China */class proxy {/* list to be collected */public $ list; /* Save the proxy list path */public $ save_path = 'proxy.txt ';/* obtain the collection list */function get_list ($ page) {$ url = 'HTTP: // www.cnproxy.com/proxy (* pai.html '; // processing list $ this-> list = preg_replace ('/\ (\ * \)/', $ page, $ url ); return $ this-> list;}/* collect proxy content */function get ($ page) {$ this-> get_list ($ page ); $ file = stripslashes (file_get_contents ($ this-> list); $ zz = '/<Tr> <td> ([0-9 \.] +) <SCRIPT type = text \/javascript> document \. write \ (":" ([\ + a-z] + )\) <\/SCRIPT> <\/td> <td> [\ w] + <\/td> <td> [\ w \,] + <\/td>/is '; preg_match_all ($ zz, $ file, $ temp); unset ($ temp [0]); $ th = array ('Z ', 'M', 'k', 'l', 'D', 'x', 'I', 'w', 'Q', 'B '); $ 2nd = array (3, 4, 2, 9, 0, 5, 7, 6, 8, 1 ); foreach ($ temp [2] as $ k => $ v) {$ v = preg_replace ("/[\ +] +/", '', $ v ); $ s = str_replace ($ th, $ YY, $ v ); $ Re. = $ temp [1] [$ k]. ':'. $ s. "\ r \ n" ;}$ this-> save ($ re); return true;}/* save */function save ($ re) {return file_put_contents ($ this-> save_path, $ re, FILE_APPEND);}/* read */function read () {return file_get_contents ($ this-> save_path );}} // initialize the collection class $ p = new proxy; $ start = 1; $ end = 10; // control if ($ _ GET ['a'] = 'start ') {echo 'sending collection request'; echo '<meta http-equiv = "Refresh" content = "3; URL =? P = 1 "> ';} elseif (isset ($ _ GET ['P']) {$ I =$ _ GET ['P'] ++; if ($ I >=$ end + 1) {exit ('<meta http-equiv = "Refresh" content = "0; URL =? A = end "> ');} else {echo 'request list '. $ I. '> '. $ end; if ($ p-> get ($ I) {echo '<meta http-equiv = "Refresh" content = "3; URL =? P = '. $ _ GET ['P'] ++. '">' ;}} elseif ($ _ GET ['a'] = 'end') {echo 'collection finished ';} else {echo '<form> <input type = "hidden" name = "a" value = "start"/> <input type = "submit" value = "start collection "/> </form> ';}?>
